peugeot 206 auto stalls when engine warms up

Hello friends. The engine runs fine when I drop the child off at school in the morning. When it gets hot, the problem of not eating gas starts. I changed the crank sensor, I changed the ignition coil. The problem still remains the same. The mechanic said he sent it to the brain mechanic. I think the 4th injector is not getting electricity. They think it will cost between 2500-3000. What do you suggest? I want to have the brain repaired. When I buy a second hand brain, it may cause problems in the future. See the video. Thanks

Hello. When the ignition coil is changed, it would be good to change the spark plugs, sir. After warming up, it may be caused by the gasoline ejectors. There is no electricity to the 4 injectors. I know for sure. Is the socket disconnected and checked?
